LOS ANGELES — Leonardo DiCaprio and Christopher Nolan's "Inception" is anything but a sleeper as the thriller opened as the No. 1 film at the weekend box office.

The Warner Bros. action tale about a team that sneaks into people's dreams is DiCaprio's biggest opening weekend, topping his previous best of $41.1 million for last winter's "Shutter Island."

"Inception" falls far short of director Nolan's best, though. Nolan is the man who directed the Batman blockbuster "The Dark Knight," which opened over the same weekend two years ago with a record $158.4 million.

Estimated ticket sales for the weekend were:

1. "Inception," $60.4 million.

2. "Despicable Me," $32.7 million.

3. "The Sorcerer's Apprentice," $17.4 million.

4. "The Twilight Saga: Eclipse," $13.5 million.

5. "Toy Story 3," $11.7 million.

6. "Grown Ups," $10 million.

7. "The Last Airbender," $7.5 million.

8. "Predators," $6.8 million.

9. "Knight and Day," $3.7 million.

10. "The Karate Kid," $2.2 million.
